The 953 area code is a relatively new addition to the North American Numbering Plan (NANP), serving a specific region within California. While its exact implementation date may vary depending on the source, it's crucial to understand its geographical coverage and implications for residents and businesses alike.

Geographical Coverage

The 953 area code primarily overlays the existing 559 area code. This means that both area codes serve the same general geographical area, primarily encompassing portions of central California. This overlay was implemented to address the growing demand for new phone numbers in the region, a common occurrence as population grows and technology advances. The specific cities and counties covered by the 953 area code can be confirmed through official sources like the California Public Utilities Commission (CPUC) or the North American Numbering Plan Administrator (NANPA). Precise boundaries should always be verified with these official resources.

Implications for Residents and Businesses

The introduction of an overlay area code like 953 means that residents and businesses in the affected regions may receive new phone numbers with the 953 prefix. Existing numbers with the 559 prefix will remain unchanged, unless a customer specifically requests a new number. This transition typically happens gradually, minimizing disruption to existing services.

It's important for individuals and companies to be aware of this overlay to avoid confusion when receiving calls or making calls within the affected area. Businesses, in particular, should update their contact information and databases to include the new 953 area code to ensure smooth communication with their clients and partners.

Ten-Digit Dialing

With the implementation of the 953 area code overlay, ten-digit dialing is likely to become mandatory within the affected region. This means that all calls, even local calls, will require dialing the area code (either 559 or 953), followed by the seven-digit phone number. This is a standard procedure for overlapping area codes to ensure proper routing of calls. It's crucial for residents and businesses to adopt this practice to avoid call routing issues.

Staying Informed

To stay up-to-date on any changes or announcements regarding the 953 area code, it's recommended to monitor announcements from your telecommunications provider and consult official sources like the CPUC and NANPA. These organizations provide the most accurate and reliable information on area code changes and their impact on residents and businesses.
